ADVERTISING-SIGN.

SPECIFICATION forming part of Letters Patent No. 477,429, dated June 21,1892. Application filed Pehrnaryl, 1892. Serial No. 419,965. (No model.)Patented in England December 14. 1888, No. 18,244.

To all whom it may concern:

Be it known that I, ARTHUR MARTYN, a subject of the Queen of GreatBritain, residing at Hammersmith, London, in the county of Middlesex,England, have invented a new and useful Improvem entin Advertising-Signs, 650., (for which I have obtained a patent in GreatBritain, No. 18,244, bearing date December 14, 1888,) of which thefollowingis a specification.

This invention relates to the class of advertising-signs which arecomposed of letters or symbols formed of sheet material and cemented orotherwise fastened to a pane of glass; and it consists in an improvedmethod of forming an advertising-sign, as hereinafter described, andspecifically set forth in the claim.

In constructing my improved advertisingsign I proceed as follows: Ifirst prepare a mold or matrix having the desired pattern or letterssunk into or raised upon its surface, and I press or stamp thin sheet1netalsuch as lead, for exam ple-or papier-mach, orother suitable moreor less plastic or ductile material, into or onto the said mold ormatrix by means of a die or follower or otherwise, so as to cause thesheet to receive the impression of the pattern or letters in or on themold or matrix without cutting or impairing the integrity of the sheet.011 removal from the mold or matrix the thin sheet metal or othermaterial will have the pattern or letters sunk into it, and this sunkpattern or these sunk letters can be gilded or colored, as required. Ithen paint on a sheet of glass in any desired color or otherwise applythereto a pattern corresponding exactly to the shape of the fieldsurrounding the letters or symbols of the sign to be produced, whichfield is the part not sunk in the stamped or molded article previouslydescribed. The part of the glass which is left clear corresponds to thesunk pattern or letters. I then place this glass over the aforesaidstamped or molded article, so that the sunk portions of the latterexactly coincide with and show through the clear parts of the glass, thepainted parts of the latter or pattern applied thereto then coming infront of and masking those portions of the article which have not beensunk, so as to ap pear to be the ground of the sign, and the design,symbols, or letters appear to have been cut deeply in said ground. Theglass and the aforesaid molded article when properly secured together bycement or otherwise form the complete sign, panel, or tablet, which maybe backed up or mounted in a suitable supporting-frame, as may berequired.

In preparing the glass it may be coated entirely on one surface with thecolor or colors, the latter being afterward removed from those portionswhich are required to be transparent by means of stencil-plates and whatis known as the brushingbut process; or the glass may be covered withsuitably-colored paper, parts of which are removed where transparency isrequired, or any other suitable means may be employed for producing asheet of glass with more or less opaque ground and transparent partscorresponding to the sunk pattern or letters. The sunk design or lettersmay be gilded or otherwise decorated after they have been impressed, orthe sheet of metal or other material may be gilded or othwise treatedprior to being molded or stamped.

In the drawings hereto annexed, Figure 1 represents a sheet of metal orother material having sunk letters and a design formed therein bypressure between a mold or matrix and a die or follower-in a manner wellunderstood.

Fig. 2 represents a sheet of glass which is left transparent at theparts corresponding to the sunk design and letters on the sheet of metalshown in Fig. 1,but the backsurface of which is colored at the otherparts, as shown by hatched lines, Fig. 3 represents the sheet of glassshown in Fig. 2 with the molded sheet of metal shown in Fig. 1 placedbehind it, so that the sunk portions in the sheet of metal show throughthe transparent parts of the glass and the desired effect is produced:namely, that the colored part of the glass represents the surface of agiven material, such as marble, slate, and so forth, and the sunkportions of the sheet of metal behind have the appearanc of a design orletters cut or carved in such material; and Fig. t is a transt ersesection on line 00 co in Fig.

lVhen employing plastic material as the base of the panel, tablet, orsign, the said plastic material may be molded in any convenient manner.For example, it may be placed in a molding box or frame and the lettersor design impressed therein, or th e said letters or design may beplaced at the bottom of the molding box orframe, and the plasticmatcrialsuch as plaster-of-paris or cement, for examplepoured orotherwise deposited onto same.

I have found that asphalt, any hard variety of pitch, papier-mach, or acomposition such as is used by picture-frame makers in the manufactureof gilt and other picture-frames and moldings form suitable plasticcompositions for the purpose of carrying out this part of my invention.

I am aware that signs, panels, and tablets have already been produced bymeans of designs orletters cut or carved in a slab of wood or othermaterial and placed behind a painted sheet of glass, the cutor carvedportions only appearing through the transparent parts of the said glass,and I make no claim to such construction; but

"What I do claim is- The method of forming an advertising-signconsisting in molding or stamping in a sheet of ductile or plasticmaterial depressions corresponding to the shape and position of theletters or symbols of the sign to be produced, placing on the back of asheet of transparent glass a pattern corresponding to the shape of thefield surrounding said letters or symbols, and placing said glass withthe said pattern upon the aforesaid molded orstamped sheet in suchposition in relation to the letters or symbols as to cause them tocoincide with the openings in the aforesaid pattern, and thus appearthrough the clear spaces of the glass and sunk away from the same, asset forth and shown. I

In testimony whereof I have hereunto signed my name this 13th day ofNovember, 1891.
